  as of 2.6.35-rc6, i ran another scan of the tree, looking for "bad"
config variable references, as in, preprocessor tests of CONFIG_
variables that aren't defined in any Kconfig file that i can see.

  it's all broken down by directory and subdirectory:

http://www.crashcourse.ca/wiki/index.php/Badref_CONFIG_variables

  as an example, here's what showed up under drivers/mmc:

>>>>> MMC_EMBEDDED_SDIO
drivers/mmc/host/msm_sdcc.c:1148:#ifdef CONFIG_MMC_EMBEDDED_SDIO
>>>>> MMC_MSM7X00A_RESUME_IN_WQ
drivers/mmc/host/msm_sdcc.h:238:#ifdef CONFIG_MMC_MSM7X00A_RESUME_IN_WQ
drivers/mmc/host/msm_sdcc.c:1060:#ifdef CONFIG_MMC_MSM7X00A_RESUME_IN_WQ

  as in, there's a test for "CONFIG_MMC_EMBEDDED_SDIO" when there is
no definition of such a variable in a Kconfig file.

  more scanning coming later, but that page covers the whole tree
looking for just that property.
